Human-Machine Interface (HMI) for power automation systems

Human-Machine Interface (HMI) for power automation systems - SICAM SCC


The process and visualization system SICAM SCC is a central element of energy automation solutions. The system is independent of the substation technology installed. SICAM SCC is compatible with the SICAM PAS Power Automation System, the products of the SICAM RTUs line. And in case you are not using a substation controller in your station: SICAM SCC communicates directly with bay units and protection devices that support the IEC 61850 communication standard. As a result it can be used as an overall HMI system for devices. The SIMATIC WinCC based SICAM SCC system is scalable and offers efficient engineering for energy automation applications at utilities and industrial enterprises.

Right from the start, SIMATIC WinCC has stood for the highest levels of openness and integration, since it has consistently backed standard technologies and software tools.




common HMI for SICAM and SIMATIC SICAM SCC is based on the SIMATIC WinCC system, one of the world leading process visualization systems, adding the functions required for use as substation operating system of the electric process in high-voltage and medium-voltage systems. The compatibility with SIMATIC WinCC allows SICAM SCC to be used as an add-on together with SIMATIC WinCC on one computer. This enables an integrated system solution for visualizing and controlling the industrial manufacturing processes using SIMATIC automation devices (e.g. S7 and PCS7) and the electric energy process (e.g. SICAM PAS). 


SICAM SCC – functions for use with SICAM and IEC 61850


SICAM SCC is tailored to be used in energy applications supporting operators with the task of optimizing system management. It provides a fast and clear overview of the system operating states. The specific properties of the HV and MV switchgear in control and monitoring direction (double commands and double-point indications) are optimally implemented in the indication lists and the graphic process visualization. 


SICAM SCC – logging that adds value


The original time stamps are logged in the indication lists in ms resolution as generated in the devices. Each indication is displayed with a number of additional information items. They provide information about the up-to-dateness of the information in the event of a device or communication failure (up-to-date/not up-to-date) or an active bay blocking or telecontrol blocking. In addition, they specify the cause of the status change (spontaneous, command) and, in case of a command, they provide information about the source of the operation (local, remote). In addition to process indications, command indications are logged, too. Each command operation is thus documented completely and in detail, from the command initiation by the operator to command output and feedback from the process after change of status of the controlled switchgear. 


SICAM SCC – from process visualization to topological coloring


IndustrialX controls are used to control and monitor the switchgear in the fully graphical process images (single-line diagrams). These switchgear objects support 4 different display modes (IEC, DIN, SINAUT LSA, SICAM) for circuit-breakers and disconnectors. In addition, project-specific bitmaps can be defined to represent the switchgear devices and link them with the objects. Setpoint flashing and spontaneous flashing plus the display of various device and communication states (e.g. up-to-date/not up-to-date, bay blocking and telecontrol blocking ...) are supported with the aim to provide reliable visualization. Measured values and switchgear states, which are no longer updated due to a device or communication failure or an active bay blocking, can be updated manually from the SICAM SCC operator station. The switchgear devices can be controlled either directly or using "Select before operate". Topological coloring is available for visualizing the process with single-line diagrams. 


SICAM SCC – shared substation automation functions with SICAM PAS Additional functions are supported when using the system in conjunction with SICAM PAS: If, for example, maintenance or tests have to be carried out for the process domain of a bay controller, it may not be desirable that status changes are actually processed by the SICAM PAS substation automation processing functions nor logged in the HMI. This can be implemented easily by activating the bay blocking function. The telecontrol blocking function can be used if you want status changes to be processed in the station but not transmitted to the higher-level control center. 


Substations are usually controlled from the higher-level control centers, whereas switching commands are to be rejected by the station's internal HMI; the switching authority is assigned to the higher-level control center. If control from the HMI is required for operational management reasons, the switching authority can be obtained. If the substation is connected to several control centers, the switching authority can also be assigned to specific channels. Additionally, different switching authorities can be used e.g. for the different voltage levels. 


SICAM SCC – reduced engineering effort


Exchanging data with the connected substations frequently involves several thousand indications, measured values and commands. SICAM SCC provides wizards which considerably facilitate the configuration of such information. The configuration tools (SICAM PAS UI Configuration, SICAM TOOLBOX II) provide the required description of the process data in electronic form and can be imported conveniently using the SCC wizards. Redundant data entries are thus avoided. SCD files can be imported for IEC 61850 device which are connected directly.
